PHP 5 Variables

Variables are “containers” for storing information:

Example

Select Code
<?php
$x=5;
$y=6;
$z=$x+$y;
echo $z;
?>

Much Like Algebra
x=5
y=6
z=x+y

In algebra we use letters (like x) to hold values (like 5).

From the expression z=x+y above, we can calculate the value of z to be 11.

In PHP these letters are called variables.
